3 Claims.

The invention relates generally to metallic receptacles and moreparticularly to can structures of the tear strip type including a tearstrip which can be wound about a key to effect an opening of the can,and it primarily seeks to provide a novel collar and mounting therefor,said collar being disposed to project from the open top of the can afterthe tear strip has been removed in position for acting as a support fora reclosure cover.

In collar cans of the type referred to it is customary to provide acollar within the upper end of the can in position for projecting fromthe open top of the can after th tear strip has been removed so as toprovide a neck extension over which the upper end of the can removed bytearing out of the tear strip can be telescoped to effect a reclosure ofthe can. It is an object of the present invention to provide a novelform of collar and a mounting therefor effective to securely position thcollar in a manner for avoiding presentation of any raw edges of metalwhich can readily be contacted by a person handling the can.

In its more detailed nature, the invention resides in providing a canstructure of the character stated in which there is provided near thetop of the can a bead structure which is S-shaped in vertical crosssection so as to provide an upper bead portion extending interiorly anda lower I bead portion extending exteriorly of the can. and a collartelescoped within the upper portion of th can and including an inwardlycurled upper end extremity projected above the tear strip, a

lower abutment shoulder for seating on the upper portion of the inwardlydirected bead portion, and a lower extremity or flange portionmechanically turned outwardly so as to project into the outwardlydirected bead portion so as to anchor the lower extremity of the collartherein and dispose said lower edge extremity in position Where itcannot readily be contacted by the hand of a user of the can.

With the above and other objects in view that will hereinafter appear,the nature of the invention will be more clearly understood by reierenceto the following detailed description, the appended claims, and theseveral views illustrated in the accompanying drawing.

In the drawing: Figure 1 is a part side elevation and part verticalcross sectional view of a can embodying the invention.

Figure 2 is a fragmentary vertical cross sectional view illustrating thecollar per se.

rected bead .portion 8 and a lower outwardly directed bead portion 9.Just above the bead structure 8, 9 the container body is scored in amanner well known in the art to provide a tear strip i0 which may bewound upon a suitable key and torn out of the can structure so as toeilect'a separation of the closure 1 and the neck portion ll of the canbody immediately below said closure in effecting an opening of the can.

In order to provide for convenient reclosure of the container, a collarI2 is mounted in the container body in position for projecting from theopen upper end thereof after the tear strip l0 has been torn away. Thepresent invention is directed principally to the structure and mountingof said collar. The collar is initially constructed in the mannerillustrated in detail in Figure 2 to include an inwardly curled upperend extremity l8 and a cylindriform main body portion terminating at itslower end in a stop shoulder l4 which merges into an inwardly curvedportion l5 conforming in curvature to the upper half of the upper beadstructure portion 8, and a downwardly extended generally cylindriformportion H3.

In the formation of the can structure the main body of thecollar I2 issnugly telescoped into the upper end of the body 5 with the stopshoulder l4 thereof resting upon the upper bead structure portion 8 inthe manner clearly illustrated in Figure 3. After the collar has beeninserted in this manner into the can body, the generally cylindriformlower extension i8 thereof is 'mechanically turned outwardly into thelower bead structure portion 9 of the body 5 so as to securely anchorthe collar in the bpdy in the manner illustrated at I! in Figure 3. Itwill be apparent by reference to said Figure 3 that the provision of theS-shaped bead structure 8, 9 permits outward turning of the collaranchoring extremity ll beyond the vertical plane in which an uprightsection of the can body 5 lies.

It will be obvious by reference to Figures 1 and 3 of the drawing thatafter the tear strip ID has been torn out in the manner well known inthe art, the upper portion ll of the can body and the attached closure 1can be lifted from the collar I2 to effect an opening 01' the container.Projection of the collar l2 above the upper extremity of the can body 5left by tearing out of the tear strip Ill makes it possible to readilytelescope the closure sk rt i I over the projecting collar portionwhenever it is desired to effect a reclosure or the container. It willbe obvious that the mechanical turning of the lower end extremity of thecollar into the lower bead structure portion 9 securely anchors thecollar in position with the stop shoulder l4 thereof solidly engagingthe upper bead structure portion 8. The positioning of the lower edgeextremity of the collar in the manner stated and the inward curling 01the upper extremity of the collar as at [3 assures against presentationof raw edge metal portions in position for being contacted by the handof a user of the container.

By making the bead structure 8, 9 S-shaped in cross section, it isunnecessary to make either bead portion of great depth, and it will bereadily appreciated that it may be found desirable to make the beadportions relatively shallow so as not to necessitate sharp bending ofmultiple wall thicknesses at the position of side seam structures.

It is to be understood that the collar herein disclosed may comprise anendless band such as would be formed from a drawn ring, or it may beshaped from a strip joined at its ends in an approved manner. An exampleof the last mentioned type of collar is shown in the copendingapplication for U. S. Letters Patent Serial Number 543,655, filed byWilliam F. Punte on July 6. 1944. When collars formed from end joinedstrips are employed, the joint or seam disclosed by Punte will be founddesirable because in this form of joint or seamthe multiple thicknessesof collar band metal are disposed only at the central cylindriform bodyof the collar and no overlapping of wall thicknesses is presented at theupper edge curl or the lower edge bend portions of the collar.

While one form of the invention has been shown for purposes ofillustration, it is to be clearly understood that various changes in thedetails of construction and arrangement of parts may be made withoutdeparting from the spirit and scope of the invention as defined in theappended claims.

We claim:

1. In a sheet metal container, a body portion, an upper end closureseamed onto the body portion, said body portion having an S-shaped beadstructure adjacent its upper and including an inwardly directed upperhead portion and an outwardly directed lower bead portion, the bodyportion between said upper bead portion and the closure being scored toprovide a tear strip, and a collar snugly fitting within the body andhaving a main body portion lying opposite and extending above and belowthe tear strip with its lower extremity resting as a stop on the upperhead portion and its upper extremity formed into an inwardly curledhead, said collar also including an integral bottom extension conformingto the curvature of the upper bead portion and terminating in a rawmetal edge extending outwardly as an anchor into the lower bead portion.

2. In a sheet metal container, a body portion, an upper end closureseamed onto the body portion, said body portion having an S-shaped beadstructure adjacent its upper end including an inwardly directed upperbead portion and an outwardly directed lower bead portion, the bodyportion between said upper bead portion and the closure being scored toprovide a tear strip, and a collar snugly fitting within the body andhaving a main body portion lying opposite and extendin above and belowthe tear strip with its lower extremity resting as a stop on the upperbead portion and its upper extremity formed into an inwardly curledhead, said collar also including an integral bottom extension conformingto the curvature of the upper bead portion and terminating in a rawmetal edge extending outwardly as an anchor into the lower head portioninto position for causing said lower bead portion to house the raw edgeextremity of said anchor extension against contact by a hand of a userof the container.

3. In a sheet metal container, a body portion, an upper end closureseamed onto the body portion, said body portion having an S-shaped beadstructure adjacent its upper end including an inwardly directed upperbead portion and an outwardly directed lower bead portion, the bodyportion between said upper bead portion and the closure being scored toprovide a tear strip, and a collar snugly fitting within the body andhaving a main body portion lying opposite and extending above and belowthe tear strip with its lower extremity resting as a stop on the upperbead portion and its upper extremity formed into an inwardly curledbead, said collar also including an integral bottom extension conformingto the curvature of the upper head portion and terminating in a rawmetal edge extending outwardly as an anchor into the lower head portionand outwardly beyond the inner diameter of the container body portion.
